The prognostic role of inflammation and hormones in patients with metastatic cancer with cachexia.

We wanted to investigate the possible etiologic factors of cachexia. Forty-six patients diagnosed with cancer cachexia and 34 healthy controls were included in the study. Serum total testosterone, free testosterone, interleukin 1 (IL) alpha and beta, IL6, tumor necrosis factor (TNF) alpha, orexin, galanin, neuropeptide Y, tumor necrosis factor-like weak inducer of apoptosis and tumor necrosis factor receptor-associated factor 6, and C-reactive protein (CRP) levels were investigated. There were 36 male and 10 female patients in the cachexia group, and 24 male and 10 female patients in the control group. Median overall survival (OS) of the cachexia group after the diagnosis of cachexia was 8 (1-25) months. There were statistically significant relationships between OS and BMI, serum CRP, TRAF-6, albumin, and LDH levels in the cachexia group. In addition to cachexia, serum CRP, testosterone, and TNF alpha levels were statistically significantly correlated with OS in refractory cachexia. TRAF-6 levels was significantly correlated with type of cancer (P = 0.02). Although cachexia presents with a multifactorial ethio-pathogenesis, few of them affect the OS. Our novel results were that serum CRP, albumin, LDH, and TRAF-6 levels have a higher association with OS in patients with cancer cachexia compared to the many other parameters. An ongoing cachexia also called refractory cachexia is a recent definition. This end-stage term of cancer duration may be predicted by decreasing serum testosterone and increasing serum TNF alpha levels, as well as serum CRP levels.

Effect of gender on coagulation functions: a study in metastatic colorectal cancer patients treated with bevacizumab, irinotecan, 5-Fluorouracil, and leucovorin.

Introduction. We designed this study to evaluate how coagulation parameters are changed in metastatic colorectal cancer (mCRC) patients treated with bevacizumab, irinotecan, 5-fluorouracil, and leucovorin (FOLFIRI). Methods. A total of 48 mCRC patients who initially received bevacizumab with FOLFIRI were eligible for this study. Thirty-four patients were analyzed at baseline and on the 4th, 8th, and 12th cycles of chemotherapy. Results. There were 19 male and 15 female patients. Baseline characteristics of the groups were similar, but women had better overall survival than men (14 months versus 12 months, P = 0.044). D-dimer levels decreased significantly after the 12th cycle compared with baseline in men but not in women. Men and women had increased levels of serum fibrinogen at the early cycles, but these increased fibrinogen levels continued after the 4th cycle of chemotherapy only in women. In addition, serum fibrinogen levels did not significantly change, but aPTT levels decreased in men. Discussion. The major finding of this study is that bevacizumab-FOLFIRI chemotherapy does not promote changes in the coagulation system. If chemotherapy treatment and the possible side effects of FOLFIRI-bevacizumab treatment are well managed, then alterations of the coagulation cascade will not have an impact on overall survival and mortality.

Acute myocardial infarction caused by filgrastim: a case report.

Common uses of the granulocyte-colony stimulating factors in the clinical practice raise the concern about side effects of these agents. We presented a case report about an acute myocardial infarction with non-ST segment elevation during filgrastim administration. A 73-year-old man had squamous cell carcinoma of larynx with lung metastasis treated with the chemotherapy. Second day after the filgrastim, patient had a chest discomfort. An ECG was performed and showed an ST segment depression and negative T waves on inferior derivations. A coronary angiography had showed a critical lesion in right coronary arteria. This is the first study thats revealed that G-CSF can cause acute myocardial infarction in cancer patients without history of cardiac disease. Patients with chest discomfort and pain who are on treatment with G-CSF or GM-CSF must alert the physicians for acute coronary events.
